Does anyone know anything about a brand of computers called Coolidge?

Q: Does anyone know anything about a brand of computers called Coolidge? I won a working one and one case on Ebay. I can’t find any Coolidge websites. I don’t have the computer yet. It’d be nice to give to some of my flat broke relatives. Maybe it’s a rare collectible. We used to have a TRS 80. tee-hee!

Then, I’m wondering how to find parts to try to learn to build a computer in the empty case. If no one ever heard of a Coolidge, how would I find parts?
